GULLY.

SPECIFICATION forming part of Letters Patent No. 649,002, dated May 8, 1900.

Applicationfiled June 26, 1896. Serial No- 597,035. (No model.)

To all whom it may concern:

Be it known that I, LEWIS SKAIFE, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Gullies; and I do hereby declare that the following is a full, clear, and exact description of the same.

Myinvention relates particularly to the cap and seat therefor that constitute the trap for the sewer-gas; and the object thereof is to provide a trap with a better seat to enable the cap to be readily removed without entering the gully and, furthermore, to improve the construction of the trap generally, and thereby impart thereto, besides the advantages just named, simplicity and cheapness of construction.

To these ends the invention may be said to consist mainly in providing for the closing of the vertical passage to the sewer connection, in connecting the cap-section freely with the seat-section, and adapting the cap-section to overlap and rest upon the seat-section, thus providing a tight joint to whatever degree either the cap or its seat may be worn.

The invention further consists in providing a gate or valve located within said vertical closed passage near the lower end thereof and adapted to be operated by the water to open and allow the entry of such water to the sewer and close and prevent the escape of sewer-gas into the gully.

Other features of novelty are embodied in my invention, as will be hereinafter pointed out, and for a full comprehension thereof and of the foregoing reference must be had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts, and wherein--- Figure 1 is a detail face view of the trap, shown in elevation and with a portion of the gully shown broken away. Fig. 2 is a transverse vertical sectional view thereof, taken on line 2 2, Fig. 1. Fig. 3 is a plan view of same, and Fig. 4 an enlarged sectional view of the upper meeting edges of the seat and cap sections.

As the gully b may be of any wellknown or approved construction, I do not illustrate the same.

The trap consists of a seat-section c and a cap-section cl, the former having a tapered outlet 0', and its inner end is slightly downwardly extended and open at the bottom, the sides of such downward extension being formed by wing-sections 0 extending to a point a short distance below the outlet. These wing-sections c are connected at their frontedges by a web 0 A frame piece or bracket 0 is formed upon the upper end of said pipe-section and carries, preferably, a pair of upwardly-curved ledges c 0 and the edge of the downwardly-inclined portion of the pipe-section and the edges of the wingsections c are preferably formed with a flange 0, the outer surface of which is inclined, as at n, which extends from the lower ends of such Wing-sections continuously around such downwardly-inclined portion of the pipe-section, all of these parts, which constitute the seat-section,being cast integrally with one another. The cap-section d is semicircularin cross-section and is open at its upper end and squared at its lower end, as at (F, while the upper end is curved and closed. The outline of the side edge of this cap is made to conform to the edge of the seat and is also preferably formed with a recess cl to receive the flange 0", whereby the cap will always overlap and be in contact with the seat. Upon the outside of the upper end of said cap is formed a staple projection d adapted to take over the upwardly-curved ledges 0 My improved gate or valve his preferably hinged adjacent to the lower end of the cap and is slightly longer than the width of the space between the cap and seat in order that it may rest upon and be supported, preferably, by a ledge a, partially on the cap and seat section, thereby completely closing the vertical passage, while the recess formed by the squared portion of the cap will accommodate the gate or valve when it is raised by the water.

It will be obvious that as the cap is con tinuallyin contact with its seat and that what-= ever amount of wear the staple may be sub jected to in swinging the cap when occasion may require (during which operation such staple and the ledges c 0 will act as a pivotal connection between the cap and its seat) the upper face of the, recess in the edge of the cap will bear tightly upon the inclined surface it of the flange c ofthe seat, and thus at all times secure a perfectly-tight joint, while the cap may nevertheless be conveniently lifted bodily from the seat by means of a hook or other instrument passed under the staple between the ledges c the bracket 0 being cut away or narrowed, as at p, to accommodate such instrument. It will be furtherobvious that the fact of a closed passage being formed to connect the lower end of the cap with the sewer connection will effectively prevent the escaping of sewer-gas into the gully so long as the lower end of such cap is submerged, and if the surface of the water in the gully sinks below the lower edge of the cap the gate h will fall with such water, thereby under all conditions securing a perfect seal. Another advantage of hinging the gate or valve h, as shown in the vertical portion of the passage, is that the prevention of all chance of pieces of wood and other floating bodies floating up and securing a lodgment between the edge of the gate and the seat, and thus likely to keep the valve open.

What I claim is as follows:

1. In a sewer-trap, aseat-section and a capscction forming a vertical passage and the cap-section completely overlapping the top and side edges of the seat-section and resting upon the top edge thereof and an inclined gate or valve hinged to the lower portion of said cap-section for automatically closing the vertical portion of the passage formed by said cap and seat sections and adapted to open away from the seat-section.

2. In a sewer-trap, a seat-section and a capsection forming a vertical passage and the cap-section overlapping thetop and resting upon such top of said seat-section and an inclined gate or valve having its lower edge hinged to the lower portion of said cap-seetion and its upper edge resting against said seat-section for automatically closing the vertical portion of the passage formed by said cap and seat sections, and adapted to open away from the seat-section.

3. In a sewer-trap, a detachable seat-section having an upwardly-projecting bracketpiece presenting a pair of supporting-ledges and a removable cap-section, the latter having a projecting staple-shaped handle portion formed at the top of same adapted to rest on the said pair of supporting-ledges which are located such a distance apartas to closely adjoin the sides of said staple-shaped handle portion and afford an open space between, and the central portion of the staple-shaped portion also affording a handle extending across such open space between the ledges whereby the cap-section may be conveniently lifted in a vertical line from the suspended position by a hook inserted beneath the sta= ple-shaped portion and between the ledges, for the purpose set forth.

4. In a sewer-trap havinga seat-section and cap-section forming a vertical passage, a gate or valve hinged to the cap-section and havin g its free end supported by the seat-section, for the purpose set forth.

5. In asewer-trap having a seat-section and cap-section forming a passage in part vertical and part horizontal, a gate or valve hinged to the cap-section andhaving its free end supported by the seat-section so as to antomatically close the vertical portion of the passage, and a ledge 02 for the purpose set forth.

6. A trap for the sewer connections of gullies or the like, consisting of a seat-section c and a cap-section, said seat-section having an integral tapered tubular outlet-section c r and its inner end slightly downwardly extended and open at the bottom the sides of such downward extension being formed by wing-sections c and a web 0 connected to said outlet-section and to the rear edges of said wing-sections for their full depth adjacent to said pipe-section and adapted to fit closely against the wall of the gully, for the purpose set forth.
